Case can't be that bad or nobody would buy them. Maybe just cause they're simpler machines (open center hyd's) they aren't super smooth? I know another guy that's run a lot of hoes and he says the JD's oil gets really hot. He liked the Fords pretty good back in the day. Another thing he didn't like on some newer hoes was the curved glass. He said it distorted your vision. He works for the City public works and is often digging around live electric and gas lines in emergencies. He got 2nd and 3rd place in the backhoe rodeo/olympics, or what ever it was called, back in the 90's. I think it may have been sponsored by Case. Anyway he has a lot hours running hoes.
Stupidest/most dangerous thing he ever saw was a gas company employee hopping in the city's brand new JD and driving right into a gas leak to put something over it or move something out of the way. He said the engine screamed to about 5000 RPM and probably did more damage in that 20 seconds than in 10 years of normal use. He just shook his head in disbelief.
